FILTER.

To will whom, it mfr/,y concern:

Be it known that I, ANDREW J. SHERIDAN, a citizen of the United States,residing at Kansas City, in the county of Wyandotte and State of Kansas,have invented certain new and useful Improvements in Filters; and I dodeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings', and to the letters and figures of referencemarked thereon, which form a part of this specification.

My present invention relatesv to a filter, and has for its object toprovide a device of the class described which may be easily and quicklyattached to and removed from a source 0f water-supply and which may beeasily and quickly cleansed of the impurities withheld by it from thewater passing therethrough. In accomplishing this object I have providedthe improved details of structure which will presently be fullydescribed, and pointed out in the claim, reference being had to theaccompanyingI drawingsI form-l ing part of this specification, in whichlike reference-numerals refer to like parts throughout the severalviews, and. in which- Figure I is a view in side elevation of a filterconstructed according to my invention. Fig. II is a top plan view ofsame. Fig. III is a vertical sectional view'on'the line III III, Fig.II. Fig. IV is a transverse sectional view on the line IV IV, Fig. I.

Referring more in detail to the parts, 1 represents the filter jacket orcylinder, which is provided with the head 2, which head has a closeconnection with one of the cylinder ends. The bottom 3 of cylinder 1 isprovided with a depending extension 4, having a central pocket thereincommunicating with the interior of the cylinder, and in said extensionis a port 5 and central perforation 6, both opening into said pocket.

7 is a rod extending through the cylinder and through a central channelin the filterstone 8, 'which stone the ro d supports by means of a nut9, having a threaded connection with the lower end of rod 7 Rod 7projects through the perforation in the cylinder extension 4 and carriesa nut 10, adapted to be tightened against the bottom of extension 4Patented Feb. 19, 1907.

for the purpose of rmly anchoring the rod and stone within the cylinder.

I-Iead 2 is provided with an extension 11, having a central pocket, and12 is a tube extending through a perforation in the side of extension 11into communication with said pocket.

13 is a supply-pipe having the branches 14 and 15, branch 14 extendingthrough the side of cylinder 1 near the top into communication with theannular chamber between the inner surface of the cylinder and the outersurface of the filter-stone, while pipe 15 extends through the extension11 of head 2 into communication with the pocket in said extension.

16 is a packing-ring fitting between head 2 on top of stone 8 for thepurpose of making a water-tight joint therebetween when the parts areproperly assembled.

19 is an outlet-pipe having a threaded connection with extension 4 andcommunicating with the pocket in said extension.

spective tubes controlling the inlet or outlet of water to the filter.

2O is a pipe opening from supply-pipe 15, through which filtered watermay ducted to a distance from the filter. 20 is a valve in pipe 20,which may be closed when it is desired to cleanse the filter byreversing the fiow through the cylinder by closing branch 14 and openingbranch 15.

Vhen in use, the parts are assembled as shown and described andsupply-pipe 13 connected with a suitable water-supply. hen arranged forfiltering, the valve 15 is closed, and cock 14 is opened to permit theflow of water into the outer chamber between the stone and the sides ofthe filter. The water fiowing into this chamber is forced through thefilter-stone into the central stone chamber and through the upperextension-pocket to tube 12, where its exit is regulated by the valve12, the purification taking place during its passage through the stone.After the filter has been in use for some time the stone becomes cloggedfrom the impurities in the water which adhere to it and cleansing isunnecessary. To accomplish this, I close valve 14 and open the valve 15,permitting the water to flow into the pocket in the upper exl tension 11and through the inlet-chamber 1'2 14, 15,vand 19 are valves on therebevcon- Y IOS and out through the stone into the outletchamber, carryingwith it the foreign matter which has been retained by the stone duringthe ltering process, which impurities are carried down into the lowerextension-pocket and out through tube 19, when the valve 19 is open forthat purpose. By permitting t heA water to flow through pipe 14 whilethe tube 19 is carrying off the impure water an additional cleansingforce will be provided for the outer surface of the stone to aid incarrying off the foreign matter which has been eX- pelled by the actionjust described. If it is desired to conduct the filtered water to a dif-I claim as new therein, and desire to secure by Letters Patent, is-

having wells projecting from both top and bottom, a solid filtering-bodylocated in said cylinder with a space between same andthe inner surfaceof the cylinder at the sides and bottom, said body having a channel ofsmall diameter extending through its longitudinal agiter, a rodextending through said channel and through the top and bottom of thecylinder, means on said rod for tightening said filtering-body againstthe top of the cylinder,

said cylinder and filtering-body, a feed-pipe opening into the well atthe top of the cylinder, and an independent outlet-pipe opening fromeach of said wells, for the purpose set forths.

In testimony whereof I affix my signature in presence of two witnesses.
